P2088Fuel & Air Metering

A Camshaft Position Actuator Control Circuit Low Bank 1

P2088 means the ECM detected a low voltage condition in the A camshaft (intake) position actuator control circuit on Bank 1. This controls variable valve timing. Causes include a short to ground, wiring problems, or a failed oil control valve.

🚗 Yes, but variable valve timing may be affected; repair it to protect performance.

MEDIUM

severity

🎯 Top Causes, Ranked by Likelihood

#1Short to ground in the actuator circuit$50-$250

35%

A pinched or chafed wire pulls the control signal low.

#2Failed camshaft oil control valve (solenoid)$60-$300

35%

An internally shorted solenoid causes a low-voltage reading.

#3Corroded or damaged connector$50-$200

20%

Corrosion creates a low-voltage path in the circuit.

#4ECM driver fault$200-$1000

10%

Rare failure of the ECM control driver.
